Decision-making is becoming increasingly complex as data expands and
resources decrease. My research centers on using prescriptive
(integer optimization) and predictive (machine learning) analytics,
together with algorithms, to effectively allocate scarce resources.
My research team and I employ mathematical modeling and the
development of methods and tools to benefit vulnerable and
marginalized individuals, groups, and populations.
The convergence of novel analytical technologies and open-source software can create solutions that improve quality of life, increase fairness, restore dignity, and make significant societal impact. Active research areas include analytics to benefit refugees and asylum seekers, survivors of human trafficking, and foster care. My research is supported by the National Science Foundation (Operations Engineering) grants CMMI-1825348, CMMI-1841893, CMMI-1935602, the Ragnar Söderberg Foundation, and others.
My research deeply influences students. Students who work with me learn the tools and techniques to develop innovative models and algorithms to tackle challenging real-world problems with significant societal impact. Through research involvement and related projects, students make contributions that expand the current boundaries of knowledge. Many earn MS and PhD degrees and go on to have productive and influential careers. If you are interested in learning more, see my CV, or email me.
I am Associate Professor of Operations and Industrial Engineering at WPI, and hold a Ph.D. in Industrial Engineering from the University of Pittsburgh. I publish in journals such as Operations Research, INFORMS Journal on Computing, European Journal of Operational Research, IISE Transactions, Decision Support Systems, Discrete Optimization, IJCAI, Socio-Economic Planning Sciences, Journal of Cleaner Production, Journal of Combinatorial Optimization, Health Systems, and Bioinformatics.
Forbes Magazine recently featured an article with a vignette on joint work with terrific colleagues Alex Teytelboym, Alessandro Martinello, Tommy Andersson, and WPI Data Science PhD student Narges Ahani on using analytics to improve refugee resettlement. We appreciate the attention to detail, as they note that our matching software Annie™ MOORE recommends match outcomes, that can then be fine-tuned by resettlement decision-makers. The associated technical report can be found at this link. We are grateful to the National Science Foundation (NSF), especially the Operations Engineering program, for their support of this research.Read More
Good news: PhD student Shima Azizi passed her qualifier this week! We are all very proud of her hard work on the topic of improving efficiency in community paramedicine. I'm grateful for both committee members, Prof. Michael Ginzberg and Prof. Sharon Johnson (pictured), as well as Prof. Brent Faber and Prof. Renata Konrad, for their support.Read More
I had the privilege of visiting the University of Toronto and speaking in their Operations Research Seminar on refugee resettlement research, joint with colleagues Narges Ahani, Tommy Andersson, Paul Gölz, Alessandro Martinello, Ariel Procaccia, and Alex Teytelboym. Thanks to Tim Chan for the invitation!Read More
Had the opportunity to present on placement optimization in refugee resettlement at the INFORMS Speaker Series of the Isenberg School of Management, University of Massachusetts Amherst. This is joint work with Alex Teytelboym, Alessandro Martinello, Tommy Andersson, and Narges Ahani.Read More
Here is a short video clip of my lightning talk presentation for the "Global Impact: The Latin American Experience" series at WPI's 2019 Arts & Sciences Week. My talk was entitled: Developing Data-Informed Holding and Judicial Capacity Levels for Asylum Seekers at the Southern Border.Watch here!
Had the privilege of speaking with Laurie Leshin, President of WPI, about the work of my research team and I in improving refugee resettlement matching, as well as matching WPI students to project centers.Read More
